First Claim
1. A system for performing robotic electrosurgery, the system comprising:
- an electrosurgery generator configured to sense the presence of a control voltage and to produce a corresponding electrosurgical signal in response thereto;
a robotic surgery system having at least one surgical instrument, the robotic surgery system configured to accept a user input whereby a desired electrosurgery signal is selected, the robotic surgery system further configured to provide a switch closure corresponding to the selected electrosurgery signal; and
an interface configured to convert the switch closure into a derived control voltage;
wherein the derived control voltage is capable of activating the electrosurgery generator when a single switch closure is provided by the robotic surgery system, and the derived control voltage is incapable of activating the electrosurgery generator when two or more switch closures are provided by the robotic surgery system.

Abstract
A connection cable is disclosed for controlling a voltage-controlled generator such as an electrosurgery generator from a controlling device such as a robotic surgery system. The cable includes a first connector adapted to connect to a voltage-controlled generator and a second connector adapted to connect to a controlling device. Within the cable is a voltage divider interdisposed between the first connector and the second connector. The voltage divider is configured to divide a reference voltage provided by the voltage-controlled generator into at least one control voltage which is selectable by the controlling device. The cable additionally includes a plurality of electrical wires which operatively connect the first connector, the second connector and the voltage divider. During robotic electrosurgery, said operating parameters can be actuated by a surgeon operating at the robotic surgical system console, which causes a corresponding control voltage to be switched to a control voltage input on an electrosurgery generator, which, in turn, generates a corresponding electrosurgical signal in response thereto.
